VQ Monitor는 객관적 및 주관적인 수치 자료 모두에 근거하여 음성 및 화상 커뮤니케이션 사용자 경험을 측정 및 수치화합니다. 전례가 없을 정도로 광범위하게 걸쳐 있는 RADVISION의 고급 기술력에 힘입어 VQ Monitor는 어플리케이션들이 최고의 음성 및 화상 품질 사용자 경험을 유지할 수 있도록 보장합니다.
RADVISION이 개발한 독자적인 VQ 알고리즘과 매소드는 RADVISION만의 고급 기술로 ITU-T 표준 G.1070을 강화합니다. RADVISION은 이미지 분석 요소를 발전시키는 데 필요한 기술들을 개발하고 화상 품질을 육안 수준에 비교해서 평가할 수 있는 자동 시스템을 개발하기 위해 데이터를 수집해 왔는데, 이 기존 데이터를 사용하는 객관적인 요소를 통합했습니다. 따라서 효과적으로 사용자 평가를 예측할 수 있습니다. RADVISION의 VQ 알고리즘이기에 이 정도의 혁신이 가능합니다.
